Abstract

MANETs(Mobile Ad-Hoc Network) are temporary networks composed of many autonomous nodes. Service discovery is the technology of finding services matching one’s needs in the network, which is crucial to the usability of MANETs. Many service discovery protocols for MANETs have been proposed, but no comprehensive comparative studies have been made. Hence, some typical service discovery protocols are analyzed and compared. The advantages and drawbacks of each protocol are analyzed. The paper provides a perspective overview on service discovery protocols for MANETs.
